We investigated the usefulness of an Endoflex tracheal tube, the tip of which can be bent forward by pulling on a wire held in the hand, for oral and nasal endotracheal intubations without a stylet, in comparison with tracheal intubation using a conventional endotracheal tube and a stylet/Magill forceps.
The study participants comprised 40 patients for oral intubation and 20 patients for nasal intubation. Each group was then divided into control and Endoflex subgroups. In the oral intubation study, controls were intubated using a standard Macintosh-type laryngoscope with a conventional endotracheal tube with adjuvant use of a stylet, whereas the Endoflex group was intubated using a Macintosh-type laryngoscope with an Endoflex tube. In the nasal intubation study, controls were intubated by a standard Macintosh-type laryngoscope with an endotracheal tube for nasal intubation. Under direct vision, Magill forceps were used to guide the tip of the endotracheal tube into the glottis. Patients in the Endoflex group were intubated using a Macintosh-type laryngoscope with an Endoflex tube.
Although haemodynamic changes during tracheal intubation did not differ between the groups, the duration of intubation was significantly shortened in the Endoflex groups in both studies.
The Endoflex endotracheal tube represents a beneficial tool for smooth oral and nasal intubation without requiring assistance or adjuvant equipment.
我们研究了一种Endoflex气管导管的实用性，该导管的尖端可通过拉动手中的钢丝向前弯曲，用于无管芯的经口和经鼻气管插管，并与使用传统气管导管和管芯/麦吉尔钳进行气管插管进行比较。
研究参与者包括40例经口插管患者和20例经鼻插管患者。然后将每组分为对照组和Endoflex亚组。在经口插管研究中，对照组使用标准的麦金托什型喉镜和传统气管导管，并辅助使用管芯进行插管，而Endoflex组使用麦金托什型喉镜和Endoflex导管进行插管。在经鼻插管研究中，对照组使用标准的麦金托什型喉镜和用于经鼻插管的气管导管。在直视下，使用麦吉尔钳将气管导管尖端引导至声门。Endoflex组患者使用麦金托什型喉镜和Endoflex导管进行插管。
尽管两组气管插管期间的血流动力学变化无差异，但在两项研究中，Endoflex组的插管时间均显著缩短。
Endoflex气管导管是一种有益的工具，可实现顺利的经口和经鼻插管，无需辅助或辅助设备。
